SAFETY-CATCH FOR PINS.

SPECIFICATION forming part of Letters Patent No. 247,228, dated September 20, 1881.

Application filed June 21, 1861. (N model.) I

To all whom it may concern:

Be it known that I, GEORGE W'. WASHBURN,

a citizen of the United States, residing at West New Brighton,in the State of New York,have

invented a new and useful Improvement in Safety-Catches for Pins, of which the following is a specification.

This invention relates to the fastenings of various styles of ornamental pins made by jewelers-such as breastpins and those of nursery or protection pin s-and more particularly to those fastenings in which a tube or thimble receives or incloses the point of the pin proper, so as to prevent accidentally or serreptitiously unpinning the same, and to prevent the point of the pin from coming in contact with the flesh.

The present invention consists in the combination of a telescopic safety-catch with an ordinary scroll-shaped fixed catch, the inner tube being the movable part, which is simply pressed inward by the finger to securely lock the pin and inclos'e its point, and drawn out by a pin-point or by the nails of a finger and thumb to unlock it, while the said fixed catch affords the requisite strength, facilitates catchin g and uncatchin g the pin, and operates as a stop to prevent the escape of said locking-tube, as hereinafter more fully set forth.

Figure 1 of the accompanying drawings is a side view of an illustrative breastpin locked. Fig. 2 is a like view of the same unfastened, and Fig. 3 is an end view of the catch from the section-line 3 3. Figs. 4 and 5 are side views of another illustrative breastpin, showing the same respectively locked and unfastened, and representing a modification of the safety-catch.

The illustrative breastpins are magnified in the several views to show the construction of their parts more clearly.

Like letters of reference indicate corresponding parts in all the figures.

B may represent a longitudinal or transverse bar or the body or back plate, and P the attaching-pin, of a breastpin or protection-pin; h, an ordinary stop-hinge uniting these parts, and c an ordinary scroll-shaped fixed catch. The latter may be quite small, so as to be inconspicuous, while it adords the requisite strength.

My telescopic safety-catch attachment consists, principally, of an outer cylindrical tube, t, provided at bottom with a stud or knob, s, to support its outer end, and an inner tube or thimble, 1?, hereinafter termed the guard-tube, constructed with a closed outerend, which may be provided either with a drilled transverse hole, a, to receive the point of a pin, as illustrated by Figs. 1 and 2, or with a knob, to, adapted to be grasped between the nails of a finger and thumb, as illustrated by Figs. 4 and 5.

The outer tube, t,has been constructed with a longitudinal slot corresponding with the opening of the fixed catch 0, and the guardtube 1? has been provided with a stop projection or stud, 8 to occupy said slot and limit the outward movement of said guard-tube. The inward movement of this part is prevented by the catch 0, which precludes its escapein this direction, as indicated in Fig. 3.

The parts will usually be made of the same metal as the remainder of the fastening, and will be proportioned and fitted to operate in the manner hereinafter stated,the guard-tube sliding in-and out with sufficient frictional resistance to movement to adapt it to remain in either of its positions, as shown but the spring of the pin P adapts it to securely hold the guard-tube when the pin is closed.

The pin is catched in customary manner, the catch 0 operating to arrest the pin when the latter is pressed inward and to direct the same into said catch 0 and into line with the guard-tube t and to retain the pin with ordinary security, should the wearer neglect to 1 press in the guard-tube.

In locked condition,as shown in Figs. 1 and 4, the point of the pin P is inclosed by the unslotted guard tube V, and the unfastening movement of the pin is thus precluded. To unlock it said guard-tube t is retracted byapinpoint or by the finger and thumb,as aforesaid, and the pin may then be sprung out of the catch in the ordinary way. The parts are now in the condition illustrated by Figs. 2 and 5. The pin is refastened in customary manner and relocked by simply pushing said guardtube t inward by means of the finger, and at all times, t, sliding longitudinallyin line with said catch when closed, the pointof the pin is effectively and stopped by the latter, and a fixed outer IO protected by being inclosed in said tube. tube forming a guide for said guard-tube, sub- Having thus described my said invention I stantially as herein specified. 5 claim as new and desire tosecure by Letters GEO. W. WASHBURN.
